GENERAL DESCRIPTION
The AD7840 is a fast, complete 14-bit voltage output D/A con-verter. It consists of a 14-bit DAC, 3 V buried Zener reference, DAC output amplifier and high speed control logic. The part features double-buffered interface logic with a 14-bit input latch and 14-bit DAC latch. Data is loaded to the input latch in either of two modes, parallel or serial. This data is then transferred to the DAC latch under control of an asynchronous LDAC signal. A fast data setup time of 21 ns allows direct parallel interfacing to digital signal processors and high speed 16-bit microprocessors. In the serial mode, the maximum serial data clock rate can be as high as 6 MHz. The analog output from the AD7840 provides a bipolar output range of ±3 V. The AD7840 is fully specified for dynamic per-formance parameters such as signal-to-noise ratio and harmonic distortion as well as for traditional dc specifications. Full power output signals up to 20 kHz can be created. The AD7840 is fabricated in linear compatible CMOS (LC 2 MOS), an advanced, mixed technology process that com-bines precision bipolar circuits with low power CMOS logic.
The part is available in a 24-pin plastic and hermetic dual-in-line package (DIP) and is also packaged in a 28-termi-nal plastic leaded chip carrier (PLCC).
PRODUCT HIGHLIGHTS
1. Complete 14-Bit D/A Function The AD7840 provides the complete function for creating ac signals and dc voltages to 14-bit accuracy. The part features an on-chip reference, an output buffer amplifier and 14-bit D/A converter.
2. Dynamic Specifications for DSP Users In addition to traditional dc specifications, the AD7840 is specified for ac parameters including signal-to-noise ratio and harmonic distortion. These parameters along with important timing parameters are tested on every device.
3. Fast, Versatile Microprocessor Interface The AD7840 is capable of 14-bit parallel and serial interfac-ing. In the parallel mode, data setup times of 21 ns and write pulse widths of 45 ns make the AD7840 compatible with modern 16-bit microprocessors and digital signal processors. In the serial mode, the part features a high data transfer rate of 6 MHz.
